Yokeless Hidden Hinge Digital Micromirror Device with Double Binge Layer

摘要

A micromirror array 110 fabricated on a semiconductor substrate 11. The array 110 is comprised of four operating layers 12, 13, 14, 15. An addressing layer 12 is fabricated on the substrate. A raised electrode layer 13 is spaced above the addressing layer by an air gap. A hinge layer 14 is spaced above the raised electrode layer 13 by another air gap. A mirror layer 15 is spaced over the hinge layer 14 by a third air gap.
